TELEPHONE INSTRUMENT Filed July 1, 1932 Patented June 6, 1933 PATENTOFFICE PAUL F. C. KRIPPENDORF, F LYNN, MASSACHUSETTS TELEPHONEINSTRUMENT Application filed July 1, 1932. Serial No. 620,457.

This invention relates to movable telephone instruments of both thereceiving and transmitting types.

Instruments of the sort mentioned are generally connected to a wall orfloor outlet by flexible connector cords. As the instruments are handledin use, it is found that these cords become badly twisted, due tomanipulation in the hand of the user, which shortens them so that theuse of the instruments becomes inconvenient, and sometimes results indamage to the cords themselves.

An object of the present invention is to avoid this difficulty, and Ihave therefore provided a novel construction of such instruments havinga member or guard, preferably in the form of a loop extending around thefingers which prevents turning of the instrument in the hand when inuse, and necessitates its replacement in the same position from which itwas taken, thus avoiding twisting the cord.

In accordance with a feature of the invention, the member or guard ismade as a sepa- 5 rate piece and is attachable to an instrument of theheretofore existing patterns.

These and other features of the invention comprising certaincombinations and arrangements of parts will be apparent from thefollowing description of a preferred embodiment of the invention shownin the drawing, in which Fig. 1 shows an ordinary desk telephonetransmitter and receiver as modified to embody the invention;

Fig. 2 shows a combined receiver and transmitter; and

ig. 3 shows attachable guards applied to the ordinary desk instrument.

In Fig. 1 the transmitter 10 and receiver 12 are generally of thefamiliar type but are provided respectively with loops 14, 16 which, inthe illustrated instruments, are molded, cast or otherwise integrallyformed 5 with the instruments carrying them. They are so shaped that thespaces 18, 20 included between them and their respective instruments areample to receive comfortably the four fingers of the hand used inholding them. These loops or guard members thus prevent rolling theinstruments in the hand While they are being held, and insure that theywill be replaced in the positions from which they were taken, thusavoiding twisting the cords 22 and 24.

Fig. 2 shows a combined receiver and transmitter 26 having a similarguard loop 28, the operation of which will be clear without furtherdescription.

Fig. 3 shows the ordinary desk receiver and transmitter equipped withattachable guards 30, 32 respectively. These may be made of any desiredsubstance, as molded fiber, shaped to embrace the part to which they areattached, and fastened in place by small screws or bolts 34, as shown.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is:

1. A telephone instrument having a guard 7 member arranged to receivethe fingers of the hand between it and the main body of the instrument,to prevent rolling the instrument in the hand.

2. A telephone instrument having a guard member attached thereto at itsends and forming an aperture shaped to receive the fingers of the hand,to prevent rolling the instrument in the hand.

3. An attachable guard for a telephone instrument shaped to form anaperture to accommodate the fingers of the hand, to prevent rolling theinstrument in the ha-nd.

' 4. A guard for a telephone instrument having means for attaching it tothe instrument, 35 and shaped, when so attached, to bound a space toaccommodate the fingers of the user, to prevent rolling the instrumentin the hand.

5. A telephone receiver equipped with a guard member extending from apoint adjacent one end of the instrument to a point adjacent the otherend, and shaped to accommodate, between it and the receiver, the fingersof the user to prevent rolling the receiver in the hand.

In testimony whereof I have signed my name to this specification.
